Shield Cup For Plasma OEM Hypertherm 45-85Amp For T65/85/105 Torch

Technical Overview of the Hypertherm 220817 Shield

The Hypertherm 220817 is a specialized mechanized shield designed for use with Duramax and Duramax Lock series torches. This component is critical for the proper operation of automated plasma cutting systems, specifically those utilizing the Powermax65, Powermax85, and Powermax105 power sources. Unlike drag shields used in handheld applications, this mechanized shield is engineered to maintain the precise standoff distance required for machine cutting, ensuring arc stability and protecting the inner consumables from molten metal blowback.

Operating within an amperage range of 15 A to 85 A, this shield offers versatility across various plate thicknesses and material types. It functions as the outer boundary of the consumable stack, directing the shield gas flow to constrict the arc and cool the nozzle. The 220817 is manufactured to tight tolerances, which is essential for maintaining the concentricity of the plasma arc; deviations in shield geometry can lead to beveled cuts or reduced consumable life. It is compatible with standard mechanized setups as well as track and XY cutting platforms.

Installation of the 220817 is straightforward, fitting securely onto the retaining cap of the Duramax machine torch. It is designed to withstand the high-heat environment of continuous industrial cutting. For operators running automated tables, using genuine OEM shields like the 220817 is recommended to preserve the validity of the torch warranty and to ensure that the ohmic contact (if applicable to the specific height control setup) functions correctly, preventing torch crashes and material damage.
